The LogicalFile Package

The LogicalFile package consists, quite economically, of a single class GATLogicaFile which does all the heavy lifting. A GATLogicaFile instance represents a set of physical files which are byte-for-byte identical but dispersed throughout the geography of network space. This GATLogicaFile is useful for the very case described above. A GATLogicaFile instance, representing a set of identical physical files, abstracts the process of deciding which of the physical files away from the user and application programmer thus lifting the burden of determining which of these many files is closest in this network geography to the desired target location. Let begin our study of this beast.
